# GPU versus CPU
|
||
|
|
|
||
|
|
- GPU stands for _Graphics Processing Unit_. Originally designed for rendering
|
||
|
|
graphics and video but now used for other applications of parallel computing
|
||
|
|
eg. machine learning.
|
||
|
|
|
||
|
|
- The standard CPU uses sequential processing whereas the GPU is designed for
|
||
|
|
parallel processing, specialising in performing many simple calculations
|
||
|
|
simultaneously.
|
||
|
|
|
||
|
|
- Harnessing the GPU requires specialised programming approaches.
|
||
|
|
|
||
|
|
- Most standard laptops and desktops (if they are not designed for
|
||
|
|
graphically-intensive tasks) incorporate graphics processing within the CPU.
|
||
|
|
The CPU chip is on the same chip as the CPU chip. This is called _integrated_
|
||
|
|
graphics processing.
|
||
|
|
|
||
|
|
- Some laptops, especially those marketed for gaming or professional work, have
|
||
|
|
a separate GPU chip. This is a more powerful graphics processor, separate from
|
||
|
|
the CPU.
